Best AGCO Licensed Ontario Casinos Offering These Top Slots in 2025

The table below details the best AGCO licensed Ontario casinos where you can play the highest paying slots featured in our 2025 toplist. It also provides details on the RTP and top features from each game.

Slots Payouts And AGCO Rules

The payback percentage for all slots played at online casinos in Ontario is regulated by the Alcohol and Gaming Commission of Ontario (AGCO) and must be at least 85%. This refers to the entire lifecycle of the machine, so it does not mean you will automatically win back 85% of wagers placed.

In the short term, anything can happen when you play, but the rules state that the machine's payout cannot change while you are playing the game, and it cannot be adjusted over weekends.

How Slot RTP And Volatility Work

Return to Player (RTP) and volatility are important aspects to consider when choosing a slot.

RTP Explained

• RTP is the percentage of all money wagered that a slot is likely to payout over an extended period.
• If the RTP is 96%, then for every $100 wagered, the game will pay out $96.
• It is not a guarantee that you will win this amount. It is the average amount the slot will pay back to players over its lifetime.

Volatility Matters

• Low volatility offers small, consistent wins
• Medium volatility slots payout more often than high volatility games, but not as often as low volatility ones. The payouts are not extremely high, but not super low.
• high volatility games may not pay out as often, but when they do, the wins are bigger.
• Volatility may determine how quickly your bankroll grows or disappears, so knowing the volatility of the game you are playing allows you to determine the risks you are willing to take.

Choosing Slots with High Payouts at Ontario Online Casinos

If you're searching for slots to play with good payouts, there are several game features you should check out. It is recommended that you look for games with high RTP percentages and good slot bonus features if you want the best payout experience in Ontario.

Maximum Wins/Payouts (Should be Good Sized)

Look for slots with high maximum payouts. As you'll see from our list, slots like Tombstone R.I.P. have a max payout of 300,000x.

High RTP Percentages

Check the RTP, as some slots like Ryse of Mighty Gods have RTPs that are over 99% which means it has an average payout of 99c for every $1 wagered.

Good Hit Frequency

The hit rate refers to the percentage of spins that may result in a win. Low volatility slots tend to offer more frequent hits, but the payouts are usually smaller compared to the larger, less frequent rewards found in high volatility slots.
